Reducing the moisture content (MC) of hybrid rice seeds during the late maturation stage will reduce seed drying costs and losses due to pre-harvest sprouting (PHS), and enable earlier harvesting. Six different dehydrating agents, (A) 20% lishougu, (B) 20% paraquat, (C) 20% diquat + assisting agents-1, (D) 20% diquat + assisting agents-2, (E) 20% diquat + assisting agents-3 and (F) 20% diquat + assisting agents-4 were used for hybrid rice seed desiccation prior to harvesting. The changes in seed moisture content (MC), seed physiology, biochemistry and seed vigour were studied after the application of the dehydrating agents. Seed viability and vigour were also tested after six months storage. The relative transcription level of 64S Hsp18.0 gene was significantly down-regulated in the control; in contrast, it was significantly up-regulated after the application of dehydrating agents. The MC of seeds harvested six days after application of dehydrating treatments A, B and F was significantly reduced, by 5.9, 7.9 and 5.3%, respectively. The activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) were significantly changed during dehydration of hybrid rice seeds. The content of soluble protein showed no significant change after the application of dehydrating treatments E and F. Dehydrating treatment F had no detrimental effect on the thousand-seed weight, germination percentage and germination energy before and after storage. The results suggest that dehydrating treatment F can be used in hybrid rice production during seed maturation.
